How do the oakland raiders go undefeated in their own division, yet not win the division?

Because there was 2 other teams in their division with a better overall record. Like Urik said you still have to play 10 other games and those matter as well. Only time that would make a difference is if all were to tie with same record then the Raiders would be the division winner then! As a Raiders fan U should be asking these 2 questions: Why did Al. Davis fire a head coach that had this team on the right path? And When is Al Davis going to sell the team to a owner that will make the right moves?
